Question

based on the data in the graph, which would most likely happen if the paramecium were placed in distilled water? the contractions would increase. the contractions would decrease. the contractions would cease altogether. the contractions would establish dynamic equilibrium.

Explanation:

Step1: Analyze the graph trend

The graph shows that as salt concentration decreases, the number of contractions per minute increases.

Step2: Consider distilled - water situation

Distilled water has a very low salt concentration. Based on the trend in the graph, when the paramecium is placed in distilled water (very low salt concentration), the number of contractions would increase.

Answer:

The contractions would increase.
